Abstract	The Atomic, Molecular and Optical (AMO) science end-station at the LCLS is being designed to capitalize on the new opportunities offered for AMO science by the unique LCLS x-ray FEL. The AMO end-station will be located on the "soft x-ray" branch line of the LCLS covering the energy range from 800-2000 eV. Kirkpatrick Baez (KB) mirrors will be used to focus the FEL beam to a small waist, thus increasing the peak power of the beam sufficiently to induce non-linear photionization phenomena. Two distinct experimental chambers are being designed, one for photoionization studies with several photoelectron and photoion spectrometers, and another equipped with a detectors for measuring scattering of the x-rays by clusters. In both cases a skimmed supersonic pulse gas jet will be used to introduce the sample into the chamber. A separate chamber will house a suite of diagnostic instruments to measure the FEL pulse parameters (pulse enegy, position, transverse profile, wavelength) on a pulse-by-pulse basis.
